Further, the above noted schedule for regulation of DG sets would come into force in the entire NCR strictly w.e.f. 01.10.2023. Retro-fitment of dual fuel kits and/ or Emission Control Devices , wherever warranted, needs to be targeted to be completed latest by 30.09.2023, failing which the use of the DG set shall not be permitted under any circumstances, anywhere in the entire NCR, even for periods not under GRAP restrictions.
Representations from industrial associations, commercial entities, business organizations and individuals were received in the Commission and the issues have been repeatedly raised during interactions including with the industrial associations and the Chambers of Commerce, and with MSMEs associations across NCR in particular citing various techno-commercial and financial constraints. In view of the technical, commercial and practical aspects and the constraints involved in emission control from DG sets and considering the practical aspects of implementation of Directions and a need to minimize pollution arising out of large scale use of DG sets across the various sectors including industrial, commercial, institutional and residential units/ premises, the extant directions on the regulated use of DG sets were comprehensively reviewed leading to the revised schedule.
The Commission again urges all stakeholders concerned including vendors for all capacities of DG sets in the NCR, to strictly adopt of the Revised Schedule for regulated operations of DG sets across all sectors in the entire NCR. NCR State Pollution Control Boards / DPCC shall ensure compliance of above directions through suitable consent mechanisms and periodic monitoring.
